Answer:
1. There exists at least one square that is not a rectangle.
2. Every segment has a midpoint.
Step-by-step explanation:
1.The given statement is: "All squares are rectangles". We have to find the negation of the statement. The statement that gives the negative meaning of the given statement is called the negation of the given statement. So the negation of the given statement is, "There exists at least one square that is not a rectangle".
2.Every segment has a midpoint.

6. Chasing Angles: Find the measure of all the missing interior and exterior angles in this figure using linear pairs, vertical angles, and triangle angle sum.
The missing angles of triangles are - 30°, 50°, 40°.
What is the angle - sum property of the triangle?
According to the triangle's "angle sum property," a triangle's angles add up to 180 degrees. Three sides and three angles, one at each vertex, make up a triangle. The sum of the internal angles of a triangle is always 180o, regardless of whether it is acute, obtuse, or right.
There are 5 triangles in the given diagram,
We will see them anti - clock wise.
All the triangles are right - angled triangle.
The measures of 1 triangle are -
90°, Let the other 2 angles be x,y
The measures of the 2nd triangle are -
Given,
60°, 90°
Using angle sum property,
The measure of third angle = 180°
= 60 + 90 + third angle = 180
third angle = 180 - 150
= 30.
The measures of 3rd triangle are -
Given,
40°, 90°
Using angle sum property,
The measure of third angle = 180°
= 40 + 90 + third angle = 180
third angle = 180 - 130
= 50.
The measures of 4th triangle are -
50°, 90°
Using angle sum property,
The measure of third angle = 180°

What is algebraic operation ?Any of the basic arithmetic operations—addition, subtraction, multiplication, division, raising to the power of a whole number, and taking roots (fractional power)—is considered an algebraic operation. These procedures could be applied to numerical data, in which case they are frequently referred to as arithmetic operations. Similar operations can be carried out on variables, algebraic expressions, and, more generally, on components of algebraic structures like groups and fields. Another way to describe an algebraic operation is as a function from the Cartesian power of a set to the same set.
Given that : Sheila made four withdrawals of each from an ATM. . She also made a $156 purchase with her check card. She then deposited her $375 salary.
It's difficult to determine the solution because we don't know how much money she had in her bank account before making 4 withdrawals, thus a like and rating would be really appreciated. We know she took out $40 four times, which is $160. She also used her card to make a $156 purchase, so when we sum the two amounts, we get $316. She then placed a check for $375 into the bank account, therefore we must deduct $316 from that sum to get at $59; but, since we deducted, Given that we end up with $59 rather than the money we wasted at the beginning, the fact that the price is higher than $316 indicates that there has been an increase.

The total charge on 8 particles is -56 units. all the particles have the same charge. what is the charge on each particle? 8units 7units -7units -8units
If the total charge on 8 particles is -56 units and all the particles have the same charge, then the charge on each particle is equal to -7 units.
The charge on each particle can be determined by division.
Division is a part of the basic operations of arithmetic which are four in number, the rest being addition, subtraction, and multiplication. It can be considered the opposite of multiplication and involves separating into equal parts or groups.
The change on each particle can be calculated by dividing the total charge units by the total number of particles. Hence,
charge on each particle = total charge units ÷ total number of particles
charge on each particle = -56 / 8
charge on each particle = -7
Therefore, the charge on each particle is equal to -7 units if all the particles have the same charge.

His budget for the incentive is $60. For this total, he can purchase "x" amount of boxes of pizza. Each box of pizza cost $9.25. Select the equation that matches the word problem.
Based on the total budget of Mr. Bell for the incentive and the cost of a pizza box, the equation that matches the word problem is 60 ≥ 9.25x
What equation is correct?The amount that Mr. Bell will spend at the most is the budget for the incentive of $60.
He will not spend more than this amount but will spend a maximum of it. This amount of $60 is therefore equal to or greater than the cost of the pizzas:
60 ≥ cost of the pizza

The blanks in the question has same value and it is equal to 9
Given data
6x + ____ =7x-____ , solution is 18
How to find the missing numberslet the missing number be in the left hand side of the equation be equal to the missing number at the right hand side of the equation and both be represented by y.
if the solution is x which is 18 we substitute for y as follows
6x + y = 7x - y
y + y = 7x + 6x
plugging in the values of x
y + y = 7 * 18 - 6 * 18
2y = 126 - 108
2y = 18
y = 9
testing y = 9 in both equations
6x + y = 6 * 18 + 9 = 108 + 9 = 117
7x + y = 7 * 18 - 9 = 126 - 9 = 117

What is termed as law of cosine?A trigonometric law: the square of a plane triangle's side equals the sum of the squares of a remaining sides minus double the the product of such sides as well as the cosine of a angle between them.
If the triangle ABC is having the sides a, b and c.
Then, the formula for law of cosine is;
c² = a² + b² - 2abcosC
Now, as per the given question;
The first step is to compute the length of the fence's third side. The following formula can be used to calculate the length of a third side:
c² = a² + b² - 2abcosC
Where a,b and c are the three sides and C is the angle forming between sides a and b.
The sides are a = 160 feet, b = 160 feet.
The angle between the sides a and b is 85 degrees.
Now, estimate for c by substituting all the value in the formula.
c² = 160² + 160² - (2 x 160 x 160)cos85
c² = 51,200 - 51200 x0.087
c = √47104
c = 217.03 feet
Now, the total length of the perimeter = 160 + 160 + 217.03
= 537.03 feet
Therefore, the total length of the perimeter of the fencing material is found to be 537.03 feet.
